That is, we need to have access to our data but also access to a version of it from some time back. Normally you would have to back up each version. A snapshot, on the other hand, works in such a way that we have our data on disks, and if we take a snapshot, let's say, every day: it will work in such a way that after we take a snashot, a so-called \"snapshot\" is created and this data is frozen. And if we make any changes, they are preserved elsewhere. If we take a second \"snapshot\" then this part is frozen and we save the data in the next place. And so on and so forth. This makes it so that we are really only storing changes. If we have a huge amount of data and change a very small amount, then having many \"snapshots\", many historical versions, we actually store relatively little data. At any time we can go back, look at the version from a day ago, a week ago, a month ago or whatever we determine.<\/p>\n<h4><\/h4>\n<p><strong>What would I like to show it on?<\/strong><\/p>\n<p>First of all TrueNAS, there is a test one installed at my place, in some configuration, to this probably three 24 GB Ram disks - for test TrueNAS is completely sufficient and a virtual machine with Windows, which will be a client of this FreeNAS. And that's where I think I'll end this entry so that you can go to the video and see how it looks in practice.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>&nbsp; &nbsp; Dzisiaj TrueNAS i snapshot\u2019y \u2013 czyli jak przestrzec si\u0119 przed zgubnymi konsekwencjami szyfrowania dysk\u00f3w oraz b\u0142\u0119d\u00f3w w postaci na przyk\u0142ad skasowania danych. &nbsp; Dlaczego snapshot\u2019y s\u0105 takie fajne?
